Malicious Website Detector Add-on

Malicious Website Detector Add-on helps you steer clear of dangerous websites before you ever click through. Instead of relying on blocklists alone, it evaluates the structure of a web address itself to spot potential threats early.

Powered by advanced machine learning techniques, the add-on examines up to 10 different URL characteristics to determine whether a site is likely to be harmful. This means it can flag suspicious pages quickly and consistently, even ones it has never seen before.

A key privacy-friendly advantage is that the detection works entirely on the URL — it never accesses any website content such as text or images. You get a fast, lightweight safety check that keeps your browsing and personal data out of harm's way.
